Predicting Vehicle Repair Operations

A method of producing vehicles comprises: in a vehicle production process, manufacturing vehicle components of different types, and assembling the vehicle components to form vehicles; creating a set of vehicle records, each being a record of one of the vehicles entering active service; performing vehicle repairs on a subset of the vehicles after they have entered active service; creating a respective record of each of the vehicle repairs, each of which comprises or indicates a vehicle age or usage value, and records a vehicle component fault identified in the vehicle repair; receiving at a data processing stage the vehicle records and vehicle repair records, wherein a predictive algorithm executed at the data processing stage processes the received records so as to, for each type of vehicle component: 1) identify a respective set of the vehicle repair records relating to that type of vehicle component, and 2) use the respective set of vehicle repair records to predict a respective number of or resource value for vehicle component faults of that type for the set of vehicle records based on: a number of vehicles recorded in the set of vehicle records, and a current age or usage of each of the recorded vehicles; comparing the predictions for the different vehicle component types to identify a problem with a particular one of the vehicle component types; and adapting the vehicle production process, so as to remedy the identified problem with the particular vehicle component type for later vehicles produced in the adapted vehicle production process.
